Kyle Tucker isn't just knocking on the door of the Major Leagues -- he's nearly knocking it down.

Tucker, the Astros' No. 1 prospect (No. 10 overall), connected on a first-inning homer as he extended his hitting streak to 15 games in Triple-A Fresno's 9-5 loss against El Paso. It was the second homer in as many days for Tucker, who finished 1-for-5 at the plate in Tuesday's contest.

After a modest first two months of his season, Tucker has erupted in June to slash .411/.450/.678 with 37 hits, including 13 extra-base hits, in 22 games. The 21-year-old outfielder is hitting .484 (31-for-64) during his hitting streak, while his overall average has jumped from .269 to .316 thanks to nine multihit performances in that span.

Meanwhile, with 12 home runs and 13 steals already this season, Tucker is well on his way toward achieving his second straight 20-homer, 20-stolen base campaign after he totaled 25 and 21, in 2017. He also ranks among the Pacific Coast League leaders with 59 RBIs (second), 59 runs scored (second), 92 hits (third) and 153 total bases (third).

• No. 27 overall prospect Kyle Wright (Braves' No. 3) allowed four runs (three earned) on four hits and three walks but also set a career high with 13 strikeouts in 5 2/3 innings in a no-decision for Double-A Mississippi. He settled down after a rocky first inning to strike out the side in order in each of the next two frames. The 22-year-old righty has pitched to a 4.11 ERA in 16 starts this season, compiling 84 strikeouts and 36 walks in 82 1/3 innings.

• No. 38 overall prospect Jo Adell (Angels' No. 1) launched his sixth homer in 11 games as well as a double to finish 2-for-4 in his third straight multihit game for Class A Advanced Inland Empire. The 19-year-old outfielder has hit 10 of his 16 homers in the 31 games since his promotion to the California League. He's hitting .329 overall, with 75 hits, 53 RBIs, and 11 steals in 56 games across two levels. Brandon Marsh also had a big game for the 66ers, as the Angels' No. 4 prospect (No. 91 overall) hit a pair of triples and scored two runs to finish 3-for-4.

• No. 50 overall prospect Matt Manning (Tigers' No. 2) allowed one earned run on eight hits in his second straight seven-inning start for Class A West Michigan. The 2016 first-rounder recorded eight strikeouts and did not issue a walk in the outing, throwing 67 of his 90 pitches for strikes. Manning, 20, owns a 3.40 ERA with 76 strikeouts and a .229 opponents' average in 55 2/3 innings (11 starts) on the season.

• Blue Jays No. 28 prospect Jonathan Davis became the first player in Double-A New Hampshire's franchise history to hit for the cycle. He accomplished feat in his first four at-bats, too, tallying a double and a home run in the first two innings, respectively, before adding a fourth-inning single and a triple in the sixth to finish 4-for-5 with three RBIs and three runs scored. The 26-year-old outfielder is hitting .307 in 70 games this season and leads the Eastern League with 86 hits.

• Braves No. 18 prospect Drew Waters hit a solo home run and went 2-for-4 out of the leadoff spot as Class A Rome edged Greenville, 4-3. It was the seventh home run of the season for the 19-year-old switch-hitter, who's hitting .298/.348/.535 with 34 extra-base hits and 11 steals in his first full season. Right-hander Freddy Tarnok (Braves' No. 24) logged a career-high four scoreless innings, mixing one hit with one walk and five strikeouts, to earn the win out of the bullpen. The 19-year-old has been excellent this season, posting a 1.26 ERA with 49 strikeouts and a .164 BAA over 35 2/3 innings (16 appearances).

• Dodgers No. 13 prospect Cristian Santana had been 0-for-20 in his previous five games before connecting on a pair of solo homers in Class A Advanced Rancho Cucamonga's 6-0 win against Lake Elsinore. The two homers pushed Santana's season total to 12, a new career high for the 21-year-old first baseman after he went deep 10 times in 54 games during an eye-opening 2017 campaign.

• Giants first-rounder and No. 2 overall pick Joey Bart hit his first pro double in his first career multihit game in the Rookie-level Arizona League. The 21-year-old backstop finished the game 2-for-3 with a walk, one day after tallying his first career knock. Playing in 57 games as a Georgia Tech junior this past spring, Bart batted .359/.471/.632 with 16 homers.

• Marlins No. 20 prospectJordan Yamamoto was lights-out once again as he improved to 4-0 in six starts by leading Class A Advanced Jupiter past St. Lucie, 1-0. Tossing seven scoreless innings for a second straight start, the 22-year-old righty scattered four hits, walked one and struck out two while throwing 61 of his 92 pitches for strikes. Yamamoto sports a 1.30 ERA and 0.89 WHIP in 34 2/3 innings this season -- his first in Miami's system after coming over from Milwaukee in the offseason Christian Yelich trade.

• Pirates No. 10 prospectTaylor Hearn fired a seven-inning shutout, allowing four hits and striking out seven, in Game 1 of Double-A Altoona's eventual doubleheader sweep of Harrisburg. It was the first shutout of Hearn's career and his second complete game after the 23-year-old left-hander was credited with a complete game in his most recent turn -- a rain-shortened, four-inning loss. Hearn has been impressive in his first Double-A campaign, pitching to a 3.28 ERA with 83 strikeouts and 28 walks in 74 innings (14 starts).

• Another big night at the plate from Rays No. 14 prospect Brandon Lowe was the difference in Triple-A Durham's 6-4 win over Charlotte. The 23-year-old hit his sixth homer in as many games, matched his season high with five RBIs and reached base four times, ultimately finishing the games 3-for-5 with a walk and two runs scored. Overall, Lowe has compiled a .289/.391/.540 batting line with a career-high 14 homers across two levels this season.

• Twins No. 11 prospectLewis Thorpe racked up seven strikeouts over 5 2/3 innings of one-run, four-hit ball in a no-decision for Double-A Chattanooga. The 22-year-old southpaw has fanned 28 batters in 19 innings over his past three starts -- highlighted by a career-best 12-strikeout effort in his most recent turn -- during which he's also lowered his 2018 ERA from 4.95 to 4.06.
